How to Automate Website Redesigns in 2026 with Replay (Video-to-Code Tutorial)

TL;DR: Automate website redesigns by using video recordings of desired user flows as input for Replay, a video-to-code engine powered by Gemini, and rapidly generate fully functional, style-injected UI code.

Website redesigns are notoriously time-consuming and expensive. Traditional methods involve countless hours of manual coding, design iterations, and frustrating communication breakdowns. But what if you could simply show the system what you want, instead of painstakingly describing it? The future of web development is here, and it's driven by video. In 2026, automating website redesigns will be streamlined by leveraging video-to-code engines like Replay.

The Problem: Manual Redesigns Are a Black Hole#

Manual website redesigns suffer from a core problem: they rely on abstract specifications and subjective interpretations. Design documents, wireframes, and user stories are all representations of the desired outcome, not the outcome itself. This leads to:

• •Misunderstandings: Developers may misinterpret design specifications, resulting in deviations from the intended design.
• •Communication Overhead: Clarifying ambiguities requires lengthy email threads, meetings, and revisions.
• •Time Delays: Iterations and rework significantly extend the redesign timeline.
• •Cost Overruns: Increased development time translates directly into higher project costs.

The Solution: Behavior-Driven Reconstruction with Replay#

Replay offers a revolutionary approach to website redesigns by leveraging video as the source of truth. Instead of relying on static mockups or lengthy specifications, you simply record a video of the desired user flow. Replay, powered by Gemini, analyzes the video, understands user behavior and intent, and reconstructs fully functional UI code.

This "Behavior-Driven Reconstruction" approach offers several key advantages:

• •Accuracy: Replay analyzes the actual user interaction, eliminating ambiguities and ensuring accurate reconstruction.
• •Speed: Automated code generation significantly reduces development time.
• •Efficiency: Streamlined workflow minimizes communication overhead and rework.
• •Cost Savings: Faster development and reduced rework translate into substantial cost savings.

How Replay Differs from Traditional Approaches#

Step-by-Step Guide: Automating Website Redesigns with Replay#

Here's a practical guide on how to use Replay to automate your website redesigns:

Step 1: Recording the User Flow#

The first step is to record a video of the desired user flow. This video should demonstrate the intended behavior of the redesigned website.

💡 Pro Tip: Use a screen recording tool with high resolution and frame rate for optimal results. Tools like OBS Studio or QuickTime Player (on macOS) work well.

Consider these points when recording:

• •Focus on User Intent: Narrate your actions while recording, explaining what you're trying to achieve. This helps Replay understand the underlying intent.
• •Show All States: Capture all possible states of the UI, including loading states, error messages, and success confirmations.
• •Multiple Pages: Record flows that span multiple pages to fully demonstrate the desired user experience.
• •Keep it Clean: Avoid unnecessary mouse movements or distractions in the recording.

Step 2: Uploading to Replay#

Once you have the video, upload it to the Replay platform. Replay supports various video formats, including MP4, MOV, and AVI.

📝 Note: Ensure you have a stable internet connection for faster uploading.

Step 3: Configuring Replay Settings#

After uploading, configure the Replay settings to optimize the code generation process. Key settings include:

• •Target Framework: Select the target framework for your redesigned website (e.g., React, Vue.js, Angular).
• •Component Library: Choose the desired component library (e.g., Material UI, Bootstrap, Ant Design).
• •Style Injection: Specify how styles should be injected into the generated code (e.g., CSS-in-JS, CSS modules).
• •Supabase Integration: Enable Supabase integration if your website uses Supabase for backend services.

Step 4: Generating the Code#

With the settings configured, initiate the code generation process. Replay will analyze the video, understand user behavior, and reconstruct the UI code. This process may take a few minutes, depending on the complexity of the video and the selected settings.

Step 5: Reviewing and Refining the Code#

Once the code generation is complete, review the generated code to ensure it meets your requirements. Replay provides a user-friendly interface for inspecting the code, making modifications, and adding custom logic.

⚠️ Warning: While Replay generates high-quality code, some manual adjustments may be necessary to fine-tune the UI and ensure optimal performance.

Step 6: Integrating with Your Project#

Finally, integrate the generated code into your existing project. This typically involves copying the code into your project's codebase and making any necessary adjustments to ensure compatibility.

Here's an example of code Replay might generate for a simple React component based on a video recording of a user interacting with a button:

typescript
// Generated by Replay
import React, { useState } from 'react';
import styled from 'styled-components';

const StyledButton = styled.button`
  background-color: #4CAF50;
  border: none;
  color: white;
  padding: 15px 32px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 16px;
  cursor: pointer;
`;

interface ButtonProps {
  onClick: () => void;
  children: React.ReactNode;
}

const MyButton: React.FC<ButtonProps> = ({ onClick, children }) => {
  const [isClicked, setIsClicked] = useState(false);

  const handleClick = () => {
    setIsClicked(true);
    onClick();
    setTimeout(() => setIsClicked(false), 200); // Simulate click effect
  };

  return (
    <StyledButton onClick={handleClick} style={{ opacity: isClicked ? 0.5 : 1 }}>
      {children}
    </StyledButton>
  );
};

export default MyButton;

This code snippet includes:

• •Styled components for visual styling.
• •A click handler that simulates a button press effect.
• •Type safety with TypeScript.

Step 7: Product Flow Maps#

Replay also generates product flow maps automatically from your video. This provides a visual representation of the user's journey through your application, highlighting key interactions and decision points. This feature is invaluable for identifying potential bottlenecks and optimizing the user experience.

The Future of Website Redesigns#

In 2026, video-to-code engines like Replay will become indispensable tools for website redesigns. By leveraging the power of AI and video analysis, these tools will automate the code generation process, streamline workflows, and significantly reduce development costs. The days of tedious manual coding and lengthy design iterations are numbered. The future of website redesigns is here, and it's driven by video.

Here's another example showing how Replay can generate a form with validation:

typescript
// Generated by Replay
import React, { useState } from 'react';

interface FormState {
  name: string;
  email: string;
}

const MyForm: React.FC = () => {
  const [formState, setFormState] = useState<FormState>({
    name: '',
    email: '',
  });

  const [errors, setErrors] = useState<{ name?: string; email?: string }>({});

  const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const { name, value } = e.target;
    setFormState({ ...formState, [name]: value });
  };

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    const validationErrors: { name?: string; email?: string } = {};

    if (!formState.name) {
      validationErrors.name = 'Name is required';
    }

    if (!formState.email) {
      validationErrors.email = 'Email is required';
    } else if (!/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(formState.email)) {
      validationErrors.email = 'Invalid email format';
    }

    setErrors(validationErrors);

    if (Object.keys(validationErrors).length === 0) {
      // Submit the form
      alert('Form submitted successfully!');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input
          type="text"
          id="name"
          name="name"
          value={formState.name}
          onChange={handleChange}
        />
        {errors.name && <p style={{ color: 'red' }}>{errors.name}</p>}
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          name="email"
          value={formState.email}
          onChange={handleChange}
        />
        {errors.email && <p style={{ color: 'red' }}>{errors.email}</p>}
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;

This example demonstrates:

• •State management for form inputs.
• •Client-side validation with error messages.
• •A basic form structure with labels and inputs.
